Iranian currency Toman (10 Rial IRR) Ten years ago, on March 1, the exchange rate was 1 USD = 3,470. Today, on March 1, the exchange rate is 1 USD = 167,950. A difference of 48 times, a massive drop of 98%. And due to long-term Western sanctions + foreign exchange controls, if you Google it, you'll only find a fixed line showing 1 USD = 4,200 Toman. People can only exchange for USD or EUR in underground markets, paying a premium. But sanctions have already caused a dollar shortage for them. This is why Bitcoin has always been the most important Plan B for Iranian citizens. Approximately 1/4 of Iran's population has been exposed to cryptocurrency. If you live in regions like Europe, North America, or East Asia where exchange rates are relatively stable, you might still question whether Bitcoin has any real significance. But if you live in a war-torn area, don't doubt it—BTC is the ultimate answer. Bitcoin is humanity's final line of defense.
